v4.0.3

feat(ui): add TailwindCSS & chart-based dashboard

Integrate Tailwind CSS for styling
Display DS18B20 temperature readings in a Chart.js line graph
Implement tab-based navigation (Dashboard, API Docs, Setup)

docs(setup): add instructions for WiFi, interval, and history

Create a Setup tab explaining how to:
    Change ssid and password
    Adjust polling interval (READ_INTERVAL)
    Update the number of stored readings (HISTORY_LENGTH)

fix(tooltip): show human-readable time in chart hover

In the tooltip callback, convert epoch values to Date objects
Use .toLocaleTimeString() for improved readability

refactor(memory): reduce history length & poll interval

Default: store 360 readings (1 hour of data at 10s intervals)
Lower risk of out-of-memory errors on ESP8266 boards
Potential to adjust these defaults if more sensors or longer history is required

chore(footer): pin footer & add MIT license link

Use flexbox (min-h-screen, mt-auto) to keep footer at the bottom
Link to MIT License in the footer
Update title & references to “Arduino Temperature Control Library”
